THis current update ends with the scene with Milla right? or is my game bugged.Edit also was i supposed to lose points with characters randomly?
It's hard to say, but probably yes. If you played the sandbox version, you should check the quests to see if they're completed for you or not. As for the VN version, yes, this is definitely the end of the patch.
It all depends on the situation. Sometimes you can influence it by choosing the right answer, and sometimes you can't. I will gradually develop this mechanic.
